Emergency Declaration

Veteran detective In Ho receives a report from a man about an airplane terrorist attack. While investigating, he finds out that the suspect boarded the KI501. Despite his phobia of airplanes, Jae Hyuk decides to go to Hawaii for his daughter. At the airport, Jae Hyuk is distracted by a suspicious man with a threatening tone walking around. The KI501 flight departs Incheon Airport and heads for Hawaii, but soon a man dies for an unknown reason, and the situation of fear and confusion spreads not only on the plane but also on the ground. Upon hearing the news, the Minister of Land, Infrastructure and Transport, Sook Hee, formed a counter-terrorism countermeasure headquarters and convened an emergency response meeting to find a way to land the KI501.

both about airplane terrorist attack one in Chinese the other Korean
and the suspenseful landing of the plain

Even though both deal with terrorism and the concept of race against time, Emergency Declaration has a more linear narrative unlike Decibel.

So they are both disaster movies, with main characters who have children.
Both about a virus spreading to innocent people and will probably bring tears to your eyes

Both disaster movies with many different characters. Although the plots are different, there are many similarities such as:
both the main characters have daughters
The are minor inconveniences at the beginning
The governmental ppl trying to save the victims

The Emergency Declaration cast is going to be on The Game Caterers special episode on July 10, 2022.

Other than the zombies, these two movies have a lot of similarities. The overall themes are the same, there's infection within a plane (eerily similar to the train), and the main character is a divorced father who is taking care of his daughter. Both movies are brilliant, and are filled with suspense.

The people against the government. Some kind of virus spreading around and killing people. The main character, a man, trying to protect a child, a girl. They are very similar, but The flu is not on a plane.

- both involve a terrorist attack and a disaster
- high suspense/thriller
- government involvement
- strong casts from both

Somewhat similar yet different situation. It has a negotiation scene; if you like those intense scenes, you might like this. 

Both thriller movies are about a crisis that took place at 36,000 feet. One is about bioterrorism while the other one is when the cockpit windshield blew out. They both tell what happened when a flight was forced to make an emergency landing.

Se você gostou de "Shinkansen Daibakuha", recomendo assistir "Alerta de emergência".

Os dois filmes seguem aquela vibe desesperadora de ataque terrorista em transporte público e com bastante suspense. O que eu achei mais legal é que ambos não focam só na sobrevivência de quem está lá dentro, mas mostram todo o caos do lado de fora: o governo tentando decidir o que fazer e a pressão política correndo solta.
A grande diferença é que um é no trilho e o outro é no céu: enquanto no clássico japonês o perigo é uma bomba num trem bala, no coreano a ameaça é um vírus mortal dentro de um avião.
